摘　　要：钻井储能系统在油气工业电气化中具有重要作用。储能电池作为核心部件存在热失控风险,储能系统的热管理至关重要。为提高电能利用效率,促进石油工业的能源替代和节能减排,解决集装箱式电池储能系统内部电池紧密排布且环境相对封闭而导致的温升问题,采用STARCCM软件对钻井储能系统进行热管理分析。通过建立系统的三维模型来提取传热和散热路径。运用计算流体动力学(CFD)仿真技术对系统内的流场和温度场进行详细分析。通过CFD仿真技术成功分析了钻井储能系统内部的流场和温度场,识别出热点区域并分析了温升的原因。基于仿真结果,对风道进行了优化设计,有效改善了电池排布区域的散热条件,降低了系统的整体温度。研究结果可为储能系统的热管理设计提供重要参考依据。The drilling energy storage system plays an important role in the electrification of oil and gas industry.As a core component,energy storage batteries have a risk of thermal runaway,and the thermal management of energy storage system is crucial.In order to improve the efficiency of electricity utilization,promote energy substitution and energy saving and emission reduction in the petroleum industry and solve the temperature rise problem caused by the tight arrangement of batteries inside the containerized battery energy storage system and the relatively closed environment,STAR-CCM software was used for thermal management analysis on the drilling energy storage system.A 3D model of the system was built to extract heat transfer and dissipation paths.Computational fluid dynamics(CFD)simulation technology was used for detailed analysis on the flow field and temperature field in the system,identifying hotspots and analyzing the reasons for temperature rise.Based on simulation results,optimization design was conducted on the air duct,which effectively improves the heat dissipation conditions in the battery arrangement area and reduces the overall temperature of the system.The research results provide important reference for the thermal management design of energy storage systems.
